The interplay between nutrition and infection is well established - poor nutrition predisposes to infection acquisition, transmission, and progression, and infectious diseases often lead to worsening of nutritional status. Timely diagnosis is key to reducing the burden of both - early detection of poor nutritional status enables low cost interventions and early diagnosis of infection decreases potential for transmission and facilitates appropriate management along with antibiotic stewardship. Point-of-Care technologies offer a significant opportunity to reduce the time to diagnosis of these pathologies in both domestic and international settings consequently preventing significant delays in clinical care, particular in low resource environments. In this talk I will discuss some of the technologies and approaches to enable point-of-care diagnostics for vitamin and micronutrient deficiencies and infectious disease related cancers like Kaposi's Sarcoma. In addition to discussion the scientific and technical aspects of the technologies, I will also discuss issues related to deployment, uptake, and user need assessment.
